Bill Clinton and Trayvon Martin's mother headline DNC speakers

When Democrats gather to nominate Hillary Clinton in Philadelphia this month, their convention will be headlined by a who's who of the party's stars, and an emphasis on unity.

With a theme of "Stronger Together," the official list of speakers released Friday includes President Barack Obama and former President Bill Clinton. Other speakers will be Sybrina Fulton and Gwen Carr, respectively, the mothers of Trayvon Martin and Eric Garner — whose deaths sparked protests about racial profiling.

The slate showcases speakers both from the establishment wing of the party represented by Clinton, and from the party's progressive wing, particularly with the choice of Clinton's Democratic primary foe, Sen. Bernie Sanders.

Other speakers on the list include Vice President Joe Biden, first lady Michelle Obama, Chelsea Clinton, and Dreamers activist Astrid Silva.

It's unclear who the keynote speaker will be. The slot is typically reserved for a rising star in the party and previously launched the career of Obama, who as an Illinois state senator delivered the speech in 2004. In 2008, then-former Virginia Gov. Mark Warner gave the address, and the 2012 honor was handed to then-San Antonio Mayor Julian Castro. Warner is now in the Senate and Castro is secretary of Housing and Urban Development.

As Democrats prepare for their convention in little more than a week, Republicans open their convention Cleveland on Monday.

GOP presumptive nominee Donald Trump's recently released convention schedule features a list that includes unconventional speakers like venture capitalist Peter Thiel and Ultimate Fighting Championship President Dana White, while Clinton's list featured a relatively more traditional lineup of the party's established leaders.
